TECHNICAL DATA
OCTAL BUFFER/LINE DRIVE; 3-STATE
IN74LV240
The IN74LV240 is a low-voltage Si-gate CMOS device and is pin and
function compatible with IN74HC/HCT240.
The IN74LV240 is an octal non-inverting buffer/line driver with 3-state
outputs. The 3-state outputs are controlled by the output enable inputs 1OE
and 2OE. A HIGH on nOE causes the outputs to assume a high impedance
OFF-state.
The IN74LV240 is identical to the IN74LV244 but has inverting
outputs.
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 1.2 to 3.6 V
• Low Input Current: 1.0 µA, 0.1 µА at Т = 25 °С
• Output Current: 8 mA at VCC = 3.0 V
• High Noise Immunity Characteristic of CMOS Devices
